All the finishing touches have been added to iOS 8 ahead of its release later this month, leading Apple to seed the final GM beta to developers.
iOS 8 GM is now available to developers in the iOS Dev Center with the public release slated for September 17th, 2014 – two days before the iPhone 6 and 6 Plus hit Apple Store shelves. The new mobile operating system will be made available to iOS users for free, and is compatible with the iPhone 4s and greater, as well as the iPad 2 and greater.
